DEVICE FOR TRANSMlTTING POWER.

Specification of Letters Patent.

To MZ 0h/om, it may concern.-

Be it known that l, Janes l. KINKEAD, a citizen oi' the United States, residing at lied ding, in the county oi Shasta and State oi California, have invented new and useful lmprovcnlents in Devices for Transmitting Power, of which the following is a specification.

My invention relates to an apparatus for the application and transmission of power.

It consists in a combination of arts, and details of construction which wil be more fully explained by reference to the accontpanying drawings, in which- Figure l is a side elevation illustrating my a paratus. Fig. 2 is a plan view of the same. ig. 3 is a side elevation showing a different ap lisation of the power.

l ly invention is illustrated as follows:

A is a lever iulcrumed as shown at Upon each side of this lever are horizontal parallel tracks 3, and upon these tracks a roller 4 is adapted to travel. The end of the lever contiguous to the roller is raised at an incline as shown at A1, so that when the roller is moved along upon its track, the central portion will bear 'upon and de ress the inclined portion A1 of the lever. his will act to raise the opposite end of the leverS and by means of anysuitable connections, as links or pitmen 5, connection may be made to transmit the movement ol the lever to any mechanism which itis desired to operate, such as a pump, a drill, or other reciprocating device.

The roller 4 may be made of any suitable or desired diameter and weight, and is here shown as connected by a pitinan 6 with a source of power. This source of ower may be a steam engine or other equiva ent motor. As here shown the pitrnan is connected with a guided cross-head 7, and this with a pistonrod 8 through which power is communicated to move the roller.

The o eration of the device will be as fol lows: T ic roller being drawn toward the motor, will press upon the inclined portion A1 of the lever, and by reason of the Weight of the roller, this end of the lever will be depressed. The rst Contact of the roller with the lever meets with such resistance as the weight or mechanism to be moved at the opposite end of the lever applies; the Weight of the roiler and the power applied to move it being sufficient to move it. As the roller moves forward upon its tracks, it depresses the inclined portion A of the lever, and thus raises the opposito end with its connected parts. As the inclined portion A approaches the horizontal position, the power necessary to move the roller over it gradually decreases, and the resniting'ei'lect upon the opposite end oi the lever is correspondingly increased. lt will also be manifest that the leverage appliedto inove the roller will he, in crient, the distance between the center of the roller and its point of contact, which ractically forms a moving iulcrnm, so that il? the roller be, for instance, sin feet in diameter, and connection between the power mechanism is made with the cen-y ter of the roller, a certain amount ofpower will be necessary to move the roller independent of the weight to be raised. If the roller be increased to say, 8 feet in diameter, with a radius of 4 feet, and the same weight as be- "fore, the leverage upon the roller will be increased, and the power necessary to move it will be correspondingly less. When the roller has completed its forward movement, and depressed the lever, it may be returned by thc return reciprocation of the motorI and the end of the lever being thus released, wiil be raised by the weight at the opposite end ci the lever.v Such a weight may be represented at 9. 0r the weight of thc moving parts may be suilicient to depress this end of the lever in unison with the return movement oi the roller.

In Fig. 3 I have shown the lever fulerurned as before at 2, and the power is then applied, and the pit-man 5 is connected with the lever A between the fulcrum 2 and the inclined end A of the lever, inakinv a lever of the second class instead of in the first case where the connecting rod is outside oi the fulcruno which forms a lever of the first class. In this case, the connection may be' made as before with any desired apparatus to he reciprocated, and the movement of the roller, depressing the lever A will depress the pitnian and connected parts. The weight Qa at the outer end of the lover A. is suiiicient to depress this end of the lever and to raise the inclined end A as soon as the roller has returned and the pressure has been relieved. As shown in Fig. 3, the roller 4 is inclosed by an outer cylinder 4a of larger diameter than the roller. This annulus 4 practically forms an endless track within which the roller 4 is movable, and while the annulus 4a rolls up on the parallel tracks 3.

IOL',

lflaving)r thus described my invention, what I claim and desire to secure by Letters Patent is- 1. An apparatus includinlcr horizontal parallel tracks, a roller adapted to travel upon said tracl, means for imparting reciprocal movelnent to the roller, and a lever fulcrumcd with relation to the tracks having an upturned end over which the roller is Inovable whereby the opposite end of the lever is raised by the forward movement of the roller.

2. In an apparatus for the application of power, a fulcrumed lever having an upwardly inclined end, tracks disposed horizontally upon each side of the lever, a roller having its outer ends resting upon the tracks and the central portion movable above the lever, means for imparting a continuous reciprocal movement to the roller whereby said roller is moved back and forth over the tracks, and over the inclined portion of the lever, and connections by which the nievemcnt of the lever may be transmitted.

3. 1n an apparatus for the application and transmission of power, a weighted roller, horizontal tracks upon which it is movable, a reciprocating?r cross head and means connecting the cross head with the roller whereby said roller is reciproeated over said track, a lever fulerumed between the tracks havinjr its central portion substantially upon theI same level therewith, and the forward end upturned at an incline whereby the movement of the roller acts to depress the inclined end, means by which said lever is connected with parts to be moved, and a weight by which the lever is returned to ils normal position when released from the roller pressure.

4. In an apparatus for thc application and transmission of power, horizontally disposed tracks, a cylii'idrical shell resting upon said tracks, a roller of smaller diameter resting upon the lower side of the shell, connections between the shell and a motor by which the parts are caused to travel backward and forward along the track, a level' fulcrumed be` tween the tracks having one end upturned at an inelillation so that the roller shall act upon this inclined end to depress it and raise the opposite end, means connectingr the lever with parts to which power is to bc transmitted, and a weight by which said parts and lever are returned to the normal position when the roller is retracted.

In testimony whereof I have hereunto sel my hand in presence of two subscribing witnesses` JAMES I. KINKI'JAD.
